vibro-meter IQS450 Proximity
Measurement System Signal Conditioner
Shaft relative vibration and gap/position measurement
chains for machinery protection and/or condition monitoring
The IQS450 S3960 204-450-000-002-A1-B23-H5-I0 functions as the high-performance signal conditioner component calibrated for TQ423 proximity measurement systems.
Non-contact measurement system based on eddy-current principle
Ex certified versions for use in hazardous areas (potentially explosive atmospheres)
Voltage or current output with protection against short circuits
Together with a compatible long-stroke probe, it forms a calibrated proximity measurement system in which each component is interchangeable. The system outputs a voltage or current proportional to the distance between the transducer tip and the target, such as a machine shaft. The target material must, in all cases, be metallic. The IQS450 signal conditioner contains a high-frequency modulator/demodulator that supplies a driving signal to the transducer. This generates the necessary electro-magnetic field used to measure the gap.
The conditioner circuitry is made of high-quality components and is mounted in an aluminium extrusion. This specific model incorporates the B23 linear calibration for TQ423 long-stroke proximity transducers (typically corresponding to a 12 mm measurement range) and the H5 internal tuning circuitry. This means it is impedance-matched exclusively for a 5-meter total system cable length (including both the probe integral cable and an EA423 extension cable). TQ4xx-based proximity measurement systems can be powered by associated machinery monitoring systems such as VM600Mk2/VM600 modules (cards), VibroSmart® modules, or by another compliant power supply.

Thermal Power Generation
Online monitoring of differential expansion (shaft-to-cylinder clearance variance) in low-pressure cylinders of large steam turbine-generator units to prevent rotor-to-stator rubbing caused by uneven thermal growth.
Nuclear Power Generation
Continuous monitoring of large-scale axial float and differential expansion for main shafts of million-kilowatt class high-pressure steam turbines in conventional islands to trigger over-limit interlock shutdowns.
Hydroelectric Power
Measurement of large axial displacement swings of the main shaft and relative shaft lift under load conditions in large Francis or Kaplan hydro-generator units.
Petroleum Refining
Wide-range axial float measurement for the main shafts of large main air blower trains in fluid catalytic cracking units (FCCU) to verify thrust bearing wear status in real time.
Coal Chemical Industry
Linear measurement of main shaft thermal expansion displacement during startup and shutdown sequences of main air compressors and booster oxygen compressors in large air separation units (ASU).
Iron & Steel & Metallurgy
Monitoring main shaft axial float displacement for high-speed, heavy-load rotating shafts in Blast Furnace Top Gas Recovery Turbine (TRT) units to provide comprehensive turbine blade protection.
As the central processing hub of the eddy-current sensor chain, this conditioner must be paired precisely with its matching TQ402 probe and EA402 extension cable based on its specific B23/H5 option configuration, ensuring the total system cable length strictly equals the calibrated 5 meters, cutting or splicing the cables in the field is strictly prohibited as it destroys the charge balance of the high-frequency modulated signal and causes measurement failure.
During field installation, the conditioner enclosure must be securely connected to a single-point ground to isolate high-frequency electromagnetic interference (EMI), and its terminal connections must be well-sealed against moisture and oil ingress.
The Vibro-Meter IQS450 204-450-000-002 is an eddy current sensor signal conditioner that converts raw high-frequency signals into linear voltage or current outputs. This specific model (A1-B23-H5-I0) is calibrated for standard industrial environments, featuring exclusive linearization for TQ423 long-stroke probes (12 mm range) and impedance-matching for a 5-meter total cable length, with excellent EMI shielding.
What product is the IQS450 S3960 204-450-000-002-A1-B23-H5-I0?
It is a non-contact eddy current sensor signal conditioner manufactured by vibro-meter (Switzerland), used to process raw high-frequency data signals collected by the probe.
How do you use a product like the IQS450 S3960 204-450-000-002-A1-B23-H5-I0?
Connect the eddy current probe end to its input via cabling, wire its output to a process control system (such as PLC/DCS) or monitoring rack, and provide the required negative DC voltage supply to output proportional linear signals.
What specific meaning does the hardware code B23 represent in the IQS450 S3960 204-450-000-002-A1-B23-H5-I0?
B23 indicates that the signal conditioner is factory-calibrated exclusively for the TQ423 eddy current probe to support a 12 mm large displacement measurement range.
What is the maximum displacement measurement range that the IQS450 S3960 204-450-000-002-A1-B23-H5-I0 typically measures with a probe?
Due to the B23 specification, when paired with a standard TQ423 probe, it typically corresponds to a large displacement measurement scale of 12 millimeters (mm).
Which industrial sectors are suitable for the IQS450 S3960 204-450-000-002-A1-B23-H5-I0?
It is suitable for process industries involving heavy rotating assets, such as thermal power generation, hydropower, nuclear energy, petroleum refining, petrochemicals, coal chemicals, and large equipment manufacturing.
